Ovulation twice in one cycle

I  currently 8 DPO and yesterday I was all wet down there all day so I checked my cervix high soft not too open and egg white mucus. Took a ovulation test and it was positive!! I just don't see how I could ovulate again that's never happened to me. Took another ovulation test this morning and it's still positive! Now usually I only get one positive for one day not two in a row!
